🕝 Hi, the current time is about a half past two in the small hours 😴.

Building native compilers is hard 🤣 Building bytecode VM / interpreters is way easier 🤣

@shinyoukai@neko.laidback.moe Very cool! 😎

@shinyoukai@neko.laidback.moe Nice! 👍

@movq@www.uninformativ.de Thanks! 🙏

O Mattermost, vem-se a saber, não é uma escolha sensata: tem vários componentes proprietários (e é pouco transparente quanto a isso)

Fico aliviado de na @d3 termos optado pelo Rocket.Chat, que embora não sendo perfeito, cumpre em tudo o que é preciso e (ainda) é software livre.

@prologic@twtxt.net This is a really cool project, that’s for sure. 👌

I need to update my profile page now that I finished my PhD… I wonder what should I write…

This animation is made with points in a Python collections.deque data structure, added by dragging the mouse (code shown bellow) 🔭 I'm currently working on a PhD at Unicamp. 🌱 I should be talking less and concentrating, but... 💬 Ask me about drawing with Python! Check out py5 and pyp5js, they bring in the vocabulary from Processing & P5js! I try to make a new drawing with code everyday, and I put the results at skech-a-day. 👯 I’d like to collaborate on open resources to teach programming. I collect tools for teaching Python in a visual output here. If you find the things I share here usefull, consider supporting my work!

@lyse@lyse.isobeef.org … I was about to write “it really is worse where you live”, then I heard the first bang out on the street. 🤣

It’s this time of the year again, where people burn money on the streets.

https://www.joanwestenberg.com/the-rime-of-the-ancient-maintainer/

@shinyoukai@neko.laidback.moe Nah it’s more like there’s a lot of repeated code, because when you go from source language to intermediate representation to machine code, well you just end up writing a lot of the same patterns over and over again. I need to dedupe this I think.

@kiwu@twtxt.net Ooof 😢 That’s rough!

The compiler technique I’m using here is to not “emit” most of the runtime if it’s actually never used in your program, and also dropping dead code in the SSA pass.

@movq@www.uninformativ.de I’ve managed to bring a simple “Hello World!” in mu (µ) (at least on macOS / Darwin / ARM64) down to ~86KB (previously ~146KB) 🥳

Hmmm I need to figure out a way to reduce the no. of lines of code / complexity of the ARM64 native code emitter for mu (µ). It’s insane really, it’s a whopping ~6k SLOC, the next biggest source file is the compiler at only ~800 SLOC 🤔

@movq@www.uninformativ.de I think I can get binaries even smaller with a bit more work and effort 🤔 But yeah still working on the native code generation (at least for macOS targets)

@prologic@twtxt.net Oh! 🤔

@movq@www.uninformativ.de Oh that’s fine, Mu can compile to native code and so far binaries. at least on macOS are in the order of Kb in size 😂

@prologic@twtxt.net That might be a challenge, at least in 16-bit Real Mode: The OS follows the model of COM files on DOS, i.e. the size of the binary cannot exceed 64 KiB and heap+stack of the running program will have to fit into that same 64 KiB. 😅 (The memory layout is very rigid, each process gets such a 64 KiB slice.)

And in 64-bit Long Mode, there is no “kernel” yet. The thing in the video is literally just a small bare-metal program.

But some day, maybe. 😃

@movq@www.uninformativ.de It’d be cool if you could get µ (Mu) running in your little toyOS 🤣 You’d technically only have to swap out the syscall() builtin for whatever your toy OS supports 🤔

Almost all photos turned out to be blurred today. That made sorting a very quick process. Delete, delete, delete, … https://lyse.isobeef.org/waldspaziergang-2025-12-26/

Seeing this run on real hardware is so satisfying, even if it’s just a small example. 😅

https://movq.de/v/ec46b8cf99/netbook.mp4

My little toy operating system from last year runs in 16-bit Real Mode (like DOS). Since I’ve recently figured out how to switch to 64-bit Long Mode right after BIOS boot, I now have a little program that performs this switch on my toy OS. It will load and run any x86-64 program, assuming it’s freestanding, a flat binary, and small enough (< 128 KiB code, only uses the first 2 MiB of memory).

Here I’m running a little C program (compiled using normal GCC, no Watcom trickery):

https://movq.de/v/b27ced6dcb/los86%2D64.mp4

https://movq.de/v/b27ced6dcb/c.png

Next steps could include:

• Use Rust instead of C for that 64-bit program?
  
• Provide interrupt service routines. (At the moment, it just keeps interrupts disabled.)

I’m still deciding if I want to watch #Pluribus. When people told me Carol only wanted to meet the English speaking “imune” people it was such a turn off… like, it sounds rather offensive…

@thecanine@twtxt.net I see 🤔 Very cool though! 😎

@prologic@twtxt.net Not even entirely sure how I did it myself, but likely a lucky combination of the new tail swirl, the legs closer to the screen being bigger and the head looking slightly to the side (eye & ear position), with bottom part of the hair, going behind the snout. The white is just an outline, around most of my works, so I don’t think that plays a part.

@movq@www.uninformativ.de @prologic@twtxt.net Holy shit, this is sooo fucking cool! :-) Wow, I absolutely love it. It’s extremely fascinating what these optimizers do.

Woof, woof, @thecanine@twtxt.net! That’s cute.

Thank you! Merry Christmas! 🎄

@movq@www.uninformativ.de I have not, thanks! <3

@prologic@twtxt.net @movq@www.uninformativ.de Oh, I take my 0°C over the 36°C anytime! Even with yesterday’s gray and windy sleet in my face. However, there are definitely more pleasant times to walk in town, I’ll give you that. For example on 0°C sunny today: https://lyse.isobeef.org/waldspaziergang-2025-12-25/

@movq@www.uninformativ.de I watched a few of these thanks to you! Very cool shit™ 😎

@movq@www.uninformativ.de Ooof that’s chilly 🥶

@prologic@twtxt.net And I froze my ass off yesterday at -5°C and strong winds. 🤣

that’s a whopping 36°C today 🥵

@dce@hashnix.club merry Christmas to you too!

@thecanine@twtxt.net Is it because you’ve used white pixels around it to sort of give it aht 3D look? 👀 Hmm? 🤔

@bender@twtxt.net It’s fun living in the future isn’t it 🤣

@prologic@twtxt.net merry Christmas! I keep forgetting you live in our future. 😅

👋 Merry Xmas 🎄 🎅

This one is a slightly more 3D looking, as well as the first one, with the tail swirled.

@movq@www.uninformativ.de Hahaha, this is hilarious! :‘-D

@prologic@twtxt.net 🎄 Merry Christmas and stuff 😅🎅

@lyse@lyse.isobeef.org Lovely! We also just had some snow. 😃 Not a lot, but still. 😅

(Lol, I totally read that as “rootfs”. 🤪)

👋 Merry (2025) Xmas y’all 🎄 Ho ho ho! 🎅

@movq@www.uninformativ.de Only the roofs are a little white. It’s also windy here. https://lyse.isobeef.org/weisse-weihnachten-2025-12-24/01.jpg

@lyse@lyse.isobeef.org Oooh, nice! ⛄ We only have cold stormy weather over here. 🥴

Indeed, tiny, tiny snowflakes coming down.

Oh, that’s cute: https://movq.de/v/046fb6ee70/s.png DuckDuckGo puts a little helmet on the duck when you search for Skyrim. (Katria is a Skyrim character.)

@lyse@lyse.isobeef.org Thanks. 😅 (Do I say that? The WM can’t answer. 🤣)

A cool new open/free #book on #CreativeCoding by Stig Møller Hansen is out!

@zvava@twtxt.net I might misunderstand what you wrote, but only hashing the message once and storing the hash together with the message in the database seems a way better approch to me. It’s fixed and doesn’t change, so there’s no need to recompute it during runtime over and over and over again. You just have it. And can easily look up other messages by hash.

Happy birthday Katrina! https://www.uninformativ.de/blog/postings/2025-12-23/0/POSTING-en.html :-)

Oh wow, there might be snow tomorrow! Probably not much, though. Let’s see.

@movq@www.uninformativ.de Maybe there’s another meaning I’m not aware of, but this doesn’t look like a shitpost to me. Congrats, I guess. ;-)

Mastodon has a “Wrapstodon 2025” now, showing you a “wrap up” of the year. Of course, a pointless funny shitpost was my most “successful” post in 2025. 😂

https://movq.de/v/b9cf9e3ca0/s.png

I just had a closer look at https://git.mills.io/prologic/mu and it motivated me to do some compiler building myself again. Hopefully, I find some time in the next free days. I’m bad at it, but it’s always great fun.

2025 end the year rewind:

Compared to only 3 new artworks in 2024 and next to no work, on other projects, this year I not only met the self-imposed goal of monthly pixelart, but exceeded it by 50%, with 18 additions in total.

Relicensed the majority of canine faction owned art and projects, under two less restrictive Creative Commons licensees*. This also applies retroactively, to everyone who used/archived our art and projects, back when the old license didn’t allow it.

Disappointed by the current state of the Internet and continued lack of competition among browsers, completely reworked the main website* and made Smol Drive** (a new image gallery project), both made to be compatible with as many web and Gemini browsers, as possible.

Oh great, I received an e-mail that my SMTP credentials have been exposed. Once again, just another shitty scanner that generates garbage reports from tests it doesn’t understand. Thank you for nothing!

}

@prologic@twtxt.net I’ve been awake at that time, didn’t notice anything. 🤔 Where was that BGP analyzer again … 😅 There’s a tool that keeps track of these things, right? I forgot what it was.

@prologic@twtxt.net @movq@www.uninformativ.de A crocodile had bitten the big submarine internet cable that connects Australia to Europe. The investigations revealed that some construction work last week accidentally tore up the protective layer around it. That went unnoticed, unfortunately, so marine life had an easy job today. For just 40 minutes, they were quite fast in repairing the damage if you ask me! These communication cables are fricking large.

Just kidding, I completely made that up. :-D I didn’t notice any outage either. But I didn’t try to connect to Down Under at the time span in question.

@movq@www.uninformativ.de From 2:50 PM to 3:23 PM AEST (+10 UTC) there was an outage. Everything went “up” on Down Detector, my EU region went offline, numerous sites were unavailable, and so on. Basically everything to/from the EU appeared to basically go kaput.

@prologic@twtxt.net Hm, I didn’t notice anything. Perhaps I was asleep? 😅

Hey EU friends 👋 wtf happened to the EU Internet today for about 40 minutes or so?

@movq@www.uninformativ.de Very nice! I often wish other languages had something similar. Sometimes, I use lambdas, but that also looks ugly and feels a bit like a misuse. Other times, just the normal blocks are enough, but it’s not the same. Especially with the mutability aspects as the article explains. Typically, I just put it in a function or ignore it if it’s just a few lines.

@movq@www.uninformativ.de Ah, cool! :-) Yeah, it’s very wild what is happening under the hood all the time.

@prologic@twtxt.net You write so much code … it’s incredible. 😅

This feels useful: Rust’s Block Pattern

@lyse@lyse.isobeef.org These tables get shuffled around every time your OS switches to another process. It’s crazy that so much is going on behind the scenes.

@lyse@lyse.isobeef.org I was surprised by that as well. 😅 I thought these were features that you can use, but no, you must do all this.

By the way, I now fixed the issue that I mentioned at the end and it works on the netbook now. 🥳

https://www.uninformativ.de/blog/postings/2025-12-21/0/netbook.jpg

Wow, @movq@www.uninformativ.de, so many tables. No idea what I expected (I’m totally clueless on this low-level stuff), but that was quite an interesting surprise to me. https://www.uninformativ.de/blog/postings/2025-12-21/0/POSTING-en.html

@kiwu@twtxt.net Ta, same to you!

There is a #Processing survey going on at:

https://docs.google.com/forms/d/e/1FAIpQLSduTT2cWlXzr7QG_g4LJ-Op6LwVTI7dtXHCGVH_FdI0BK00qg/viewform

I’m happy it mentions #py5 at some point.

At the end there is this invitation for the Processing Discord server. I find it unfortunate that the Processing Foundation is moving the community towards a closed, opaque platform controlled by a corporation, when they have the open and searchable forum powered by Discourse. I wish I understood the reasoning. I know Discord can be “convenient” but IMHO the downsides are much bigger.

@movq@www.uninformativ.de @kiwu@twtxt.net it just so happens to be a happy coincidence that I’m extending mu’s capabilities to now include a native toolchain-free compiler (doesn’t rely on any external gcc/clang or linkers, etc) that lowers the mu source code into an intermediate representation / IR (what @movq@www.uninformativ.de refers to as “thick layers of abstractions”…) and finally to SSA + ARM64 + Mach-O encoder to produce native binary executables (at least for me on my Mac, Linux may some later?) 🤣

@shinyoukai@neko.laidback.moe But I thought Alpine was one of the good distro’s left. 😢 What’s it doing wrong?

@kiwu@twtxt.net Assembly is usually the most low-level programming language that you can get. Typical programming languages like Python or Go are a thick layer of abstraction over what the CPU actually does, but with Assembler you get to see it all and you get full control. (With lots of caveats and footnotes. 😅)

I’m interested in the boot process, i.e. what exactly happens when you turn on your computer. In that area, using Assembler is a must, because you really need that fine-grained control here.

@movq@www.uninformativ.de Oh, a table of contents is indeed a great idea!

Note to self: check if pygments can generate SVG, test and/or find another way to incorporate nicely formatted code into a py5 sketch… #python

@kiwu@twtxt.net Finally doing some Assembler again. 😅 Just a tiny little bit at least.

@lyse@lyse.isobeef.org Yeah, well, given that I didn’t need this for such a long time, it’s probably not an essential tool. 😅

I’ve often wanted to have an outline of text documents, though, and tagbar/ctags can do that as well:

https://movq.de/v/3c6d1a13d6/tagbar-md.png

@movq@www.uninformativ.de Interesting. I never found a big use for these kind of lists in general. But I might give it a shot again.

@movq@www.uninformativ.de Not sure what it had in its beak. It looked a wee bit like a large biscuit. But it must have been rock-hard.

@kiwu@twtxt.net I’m doing great, how’re ya going? Just two more days and then I never have to work anymore. In this year.

I just baked two trays of gingerbread. One definitely good one and another experiment.
